STREET-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 536,600, dated April 2,1895.

Application filed March 27, 1894:. Serial No. 505.266. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR CAMERON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Street-Sprinklers, ofwhich the following is a specification.

My invention relates to nozzles for street sprinklers, and sprinklersgenerally, but is particularly adapted for the former.

In a sprinkler nozzle characterized by my invention,the nozzle is closedat one end and back of such closed end it is provided with a sidedischarge opening which is formed through and arranged to extendpartially around the nozzle. In conjunction therewith, I provide a valvedevice which can be adjusted so as to either vary the thickness of thesheet of water discharged, or cut off the discharge altogether. I alsoprovide a second valve device which can be adjusted to vary the lengthof the discharge opening and hence vary the width of the sheet of waterissuing from the same. The two valve devices are conveniently under thecontrol of an attendant, and can be adjusted with reference to thedesired quantity of the discharge andcharacter of the same. In a streetsprinkler for example,one or more of these nozzles may be employed, itbeing preferable to provide two, so that one may be at each rear cornerof the cart or vehicle, whereon the tank is mounted.

In the accompanying drawings,-Figure 1 represents in side elevation, asprinkler nozzle embodying my invention. Fig. 2 is asection takenlongitudinally through the same. Fig. 3 is a cross section on line 00-90in Fig. 2, the outer valve being in position to open the side dischargeopening'a to its fullest extent. Fig. 4 is a like view with the openinga contracted in length and lever G omitted. Fig.

'5 shows the sleeve adapted to form the outer valve device. Fig. 6 is aView similar to Fig. 5, showing the transverse slot stepped or graduatedat one end only.

It is understood that the nozzle A can be connected in any suitable waywith the tank of a street or like sprinkler, and that the pipe formingsuch nozzle can have its end a expipe or nozzle is closed by an end capB, and

hence, that when the 'nozzle is supplied with water under pressure, alateral discharge of water in sheet form will, take place from thedischarge outlet a. t

In order either entirely to close the discharge outlet, or to vary thewidth of the same so as to vary the thickness of the sheet of waterdischarged, I provide a piston valve 0, which is arranged within thenozzle and adapted for adjustment to an extent to either close thedischarge opening or vary the same in width. This valve is convenientlyprovided with a stem D which extends through a stuffing box orbearing 1) in the end cap B, and engages an operating lever E. The cap Bis also conveniently provided with a bearing b for said lever whichlatter can be operated so as to adjust the valve and thereby cause thecylindric end portion 0 of said valve to close overso much of thedischarge slot at as may be desired. The cap B can be screwed upon theend of the pipe or nozzle A, thus rendering it easy to introduce thevalve within the nozzle, and also rendering it easy to remove the same.The discharge slot at can also be varied or adjusted in length so as tovary the width of the sheet of water discharged therefrom. To such end Iprovide a valve device, which can be adjusted for the purpose ofadjusting the length of the discharge slot, independently of anyadjustment on the part of the valve 0 for varying the width of slot, inwhich way the width and thickness of the sheet of water discharged fromthe nozzle can be regulated at will;

The valve-device which I have shown for opening, consists of a sleeve Ewhich is provided witha graduated openingf (best shown .in Fig. 5) andadjustably arranged upon the pipe or nozzle A, The graduated openingshown is in effect a series of part annular slots 1 oc however, involvesas hereinafter set forth a.

single opening which at different points varies in width transversely tothe length of the sleeve, thereby providing the sleeve with a graduatedopening for varying the length of l the discharge opening in the head ornozzle. For example, should the sleeve be adjusted so as to bring theportion of its opening between walls f, f, over the discharge slot, thelength of the latter will be limited to the distance between said endwalls f, f, while on the other hand, should the sleeve be adjusted so asto bring the portion of its opening between Walls f ,f over thedischarge slot, the latter will have a greater length of discharge area.This is further illustrated in Fig. 4 wherein the sleeve is in positionto considerably contract in length the discharge area of the dischargeopening a As a means for adjusting this outer valve or regulatingdevice, it is provided with lugs or journals f for the prongs of aforked adjusting lever G arranged to straddle .0 f, f and f at one endonly.

ment I find particularly desirable Wh ere I provide a wheeled streetsprinkler with two nozzles projecting respectively from opposite sidesof the tank, and in such case the graduated or stepped portion of thesleeve can be arranged for contracting or closing the discharge openingat the side of the sprinkler, that is to say,.at the side which will benearest the sidewalk when running along a street. When therefore, thesprinkler passes close to the, sidewalk, the fan-shaped discharge ofwater can be contracted or out OK at the aforesaid side so as to avoidthrowing water upon the sidewalk.

For certain purposes, the steps or graduations can be altogetheromitted, and while I regard the same as matters of special improvement,I do not for the broader purposes of my invention limit myself to sucharrangement.

What I claim as my invention is- 1. The combination in asprinkler of thenozzle having a transversely arranged oblong discharge opening,andavalve device adapted for varying the length ofsaid discharge openingand to such endhaving a graduated opening for registering with anddetermining the length of the discharge opening, according to theadjustment of the valve device substantially as described.

2. The combination with the nozzle haying a transverse dischargeopening, of a sleeve arranged for adjustment upon the nozzle and havingagraduated opening for varying the length of the discharge opening,substantially asdescribed;

3. The combination. with the nozzle having a side discharge opening, ofthe sleeve adjustably arranged on the nozzle and having a graduatedopening for regulating the length of the discharge opening in thenozzle, and a lever engaging said sleeve, substantially as described.
